| Abstract: | This note is concerned with the output dynamical feedback stabilization for linear systems with distributed delay. Based on the model transformation of neutral type, we properly construct and compute a Lyapunov-Krsovskii functional by using a special analytic method, and establish the delay-dependent stability criterion for the transformed closed-loop systems. Then, combining this stability criterion with the parameterization of controller, we develop the design condition for the desired controller in terms of linear matrix inequality through which the controller is explicitly formulated. A numerical example is given to illustrate the effectiveness of the proposed approach. |
